Tokyo, July 1 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000061946) titled 'Study of Peroneal Muscle Function and Compensatory Movements in Individuals with Chronic Ankle Instability' on June 30.

Study Type: Interventional

Study Design: Basic Design - Parallel Randomization - Non-randomized Blinding - Open -no one is blinded Control - No treatment

Primary Sponsor: Institute - Niigata University of Health and Welfare

Condition: Condition - Lateral Ankle Sprain Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - The purpose of this study is to clarify the morphological differences in the peroneal muscle group (peroneus longus and peroneus brevis) in subjects including those with chronic ankle instability (CAI), and to evaluate muscle activity during maximal voluntary contraction and torque-maintenance tasks under controlled conditions using a dynamometer. Basic objectives2 - Others

Intervention: Interventions/Control_1 - Muscle morphology of the lower leg muscles is assessed using ultrasound imaging. Surface electromyography is used to record muscle activity during strength measurements. Interventions/Control_2 - Isometric ankle eversion tasks, including maximal voluntary contraction and torque maintenance tasks, are performed using a dynamometer to assess torque and muscle activity of the lower leg muscles.

Eligibility: Age-lower limit - 18 years-old = Gender - Male and Female Key inclusion criteria - CAI Group (Chronic Ankle Instability)

1. A history of at least 1 ankle sprain. 2. Presence of "giving way", recurrent ankle sprains, or a subjective sense of instability, or meeting the cutoff scores of recommended questionnaires: CAIT = 5 "yes" responses including a history of ankle sprain IdFAI >= 11

Coper Group

1. A history of at least 1 ankle sprain. 2. No recurrent ankle sprain for at least 1 year since the initial sprain. 3. CAIT >= 28 and/or IdFAI = 28 and/or IdFAI <= 10. Key exclusion criteria - 1.Individuals with a history of fracture or surgery involving the foot or ankle. 2.Individuals presenting with lower limb injury, pain, or neurological disorders at the time of consent. Target Size - 240

Recruitment Status: Recruitment status - Preinitiation Date of protocol fixation - 2026 Year 06 Month 17 Day Anticipated trial start date - 2026 Year 06 Month 30 Day Last follow-up date - 2029 Year 03 Month 31 Day
